[Rare cases of bladder stones]

Area of Science:

• Urology
• Nephrology

Background:

• Urolithiasis, or stone formation in the urinary tract, can present with diverse clinical manifestations.
• Bladder stones (vesical calculi) are less common than kidney stones but can lead to significant complications.

Observation:

• A 63-year-old patient presented with a giant bladder stone causing severe renal insufficiency, despite lacking typical symptoms like renal colic or hematuria.
• An 85-year-old male with prostatic enlargement was incidentally found to have two star-shaped bladder stones during trans-vesical prostatic adenomectomy, with no prior symptoms.

Findings:

• Giant bladder lithiasis can precipitate severe renal impairment.
• Bladder stones may be asymptomatic, even when associated with prostatic enlargement.

Implications:

• These cases underscore the importance of considering urolithiasis in patients with unexplained renal insufficiency or during procedures for other lower urinary tract symptoms.
• Recognizing varied presentations of bladder stones is crucial for timely diagnosis and management to prevent complications.
